RPM recently announced their new Oversized Rear Axle Carriers for the Helion Volition and Criterion! As the name implies, these Oversized Axle Carriers utilize larger 5x11mm ball bearings (not included) to replace the stock 5x10mm bearings. One millimeter in diameter may not seem like much but that little change nearly doubles the load and fatigue ratings over the stock bearings. That means better performance, longer life and more time between maintenance periods.

Secondly, RPM designed the Helion Volition/Criterion Oversized Rear Axle Carriers to outlast, outperform and outshine the stock versions. They eliminated the stock camber spacer and bumped up the amount of material supporting the camber pivot ball. More threads equal more durability! Each set of RPM rear axle carriers is molded from an ultra durable engineering grade nylons to keep you rolling when everything else would have fallen apart!
